VENTILATOR FOR CARS, 80c.

SPECIFICATION forming part of Letters Patent N0. 230,011, dated. July 13, 1880.

Application filed March 6, 1880. (No model.)

To all whom it may concern:

Be it known that we, JOHN R. HAYDEN and WILLIAM H. THIELL, of Bloomington, in the county of McLean, and in the State of Illinois, have invented certain new and useful Improvements in Ventilators for Cars, Vessels, and Buildings; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and'to the letters of reference marked thereon, making a part of this specification, and in whichv Figure 1 is a front elevation, partly in section 5 Fig. 2, a central vertical section.

Our invention relates to certain new and useful improvements in ventilators for cars, ships, and buildings; and the invention consists in the general construction, combination, and arrangement of parts, all as will be here inafter fully described, and specifically-poi n ted out in the claims.

In the drawings, A represents a section of a car,showin g our improvements as applied thereto. B represents a tube extending through the top of the car down toward the bottom or floor thereof, said tube being made flaring from the top toward the bottom and having secured on the top end thereof a double-mouthed funnel, O, for the reception of the air in either direction the car is moving; and D represents a valve for closing one of the mouths of said funnel, so that the air received therein will pass down the tube B. This valve is provided with two stems, d d, passing through the central openings, 0 c, in the cross-bars c 0, arranged near the mouths of the funnel, and said valve is adapted to be automatically moved to close the mouth at either end of the funnel by the motion of the car and the resistance of the air when the car is moving.

The lower end of the tube B communicates with and terminates in a vertical conical portion, 1), inside of an outlet-tube, F, passing up through the top of the car and provided with a revolving hood, F, adapted to be turned so that its mouth is always away from the wind.

The air received in the funnel 0 passes down the flaring or contracted upper portion of the tube B with great velocity, and up through the conical portion 1) thereof, and the air being th us contracted passes directly upward through the end b with increased or great velocity into the tube F out and'through-the revolving hood F. The air passing through the conical portion of the tube B with increased velocity creates a partial-vacuum in tube F, which exhausts the foul air near the bottom or floor of the car through register f into the tube F, from which it passes out at the top through the revolving hood with the air from tube B.

G represents a pipe connecting tube B with tube F. and which pipe also terminates inside of the latter tube in a vertical conical portion, 9, said pipe G being provided with a pivoted damper, g, adapted to be turned so as to close either the tube B or the pipe G.

H represents a receptacle forming a portion of the tube F, provided with a register, h. Said receptacle is designed to be located above the car-window, or at any other convenient point in a car, vessel, or building, and is for the purpose of permitting air, dust, 850., to be exhausted therein, and discharged out through tube F, in the manner hereinafter described, said tube F being provided with a pivoted damper, h, just below the receptacle H, for closing said tube below the receptacle when desired.

When it is desired to exhaust the foul air at or near the bottom of the car the damper g is turned so as to close pipe G, which permits the air entering tube B to pass down and thence through conical portion 1) into tube F, thus exhausting the foul air, &c., through register f, into tube F, out and through revolving hood F, in the manner above explained.

When it is desired to cool the car or let off heat and not exhaust the foul air, 850., at the bottom or floor of the car, damper g is turned so as to close tubeB just below pipe G, so that the air entering tube B passes into pipe Grand out through the conical portion thereof into tube Fwith increased velocity, and the damper h being turned to close the tubeF below the receptacle H, and the register in said receptacle opened, a partial vacuum will be produced in the pipe F by the increased velocity of the air from tube B passing through the conical portion of pipe G, thus exhausting the warm air and dust in the car into and through the receptacle H into pipe F, and thence out through the revolving hood F.

We do not desire to be limited to the exact form or construction of ventilator herein shown, which is more especially designed for cars, as with slight changes it can be as well applied to vessels and buildings, except in the latter case the receiving-funnel O would have to be arranged so as to open to the wind.

The tube 13 below the pipe G may be left ofi' and closed up at that point, if desired, thus causing all the air entering the tube B to pass through pipe G into tube F and out through the revolving hood F. In this event the air can be drawn through both register f and receptacle H by opening the damper h and register h, or through either one by closing register h or damper h.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a ventilator for cars, vessels, or buildings, the combination of the air-receiving tube B, pipe G, having the conical or converging portion g, exhaust or discharge shaft or tube F, provided with the receptacle H, having register it, and the damper h, substantially as and for the purpose herein shown and described.

2. In a ventilator for cars, vessels, or buildings, the combination of the air-receiving tube B, pipe G, having the conical or converging portion g, exhaust or discharge tube or shaft F, having the receptacle H, provided with re ister h, and the pivoted dampers g h, all arranged to operate substantiallyin the manner as and for the purpose herein shown and described.

3. In a ventilator, the combination of the air-receiving tube B b, exhaust or discharge tube or shaft F, provided with register f, doubled mouthed receiving-funnel 0, having sliding valve 1), and the revolving dischargehood F, substantially as described.

In testimony that we claim the foregoing we have hereunto set our hands this 25th day of February, 1880.
